SPECIFICATION forming part of Letters Patent No. 679,075, dated July 23,1901. Application filed February 25,1899. Serial No. 706,828. (Nomodel.)

To all whom it may concern.-

Be it known that I, DANIELW. HARPER, a citizen of the United States,residing at Memphis, in the county of Shelby and State of Tennessce,have invented certain new and useful Improvements in Cash-Registers; andI do declare the following to be a full, clear, and eX- actdescriptiouof the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specifica tion.

This invention relates to new and useful improvements in cash-registers,and especially to a rotary register in which a totaladding mechanism isemployed which is actuated at each operation of the machine in effectinga registration; and in carrying out the invention it is my aim togenerally improve upon my cash-register upon which I have made anapplication for Letters Patent, Serial No. 657,268, embodying principleswhich are brought into combination with the features forming thesubject-matter of the present application.

The invention relates, further, to the provision of a total-addingmechanism which is actuated automatically as the extensibleoperating-shaft is moved longitudinally, means being provided to cause atype-wheel to be rotated, so as to present the type for the amount ofthe registration in a suitable position in which a printing-strip mayreceive an impression from said type by means of a platen, which isactuated by the pulling out of the operating-shaft, striking the stripof paper to be printed and forcing the latter against the face of thetype, between which and the platen is interposed a suitable inkedribbon. In connection with the check-printing mechanism I provide meansfor advancing the strip of paper receiving the impression and forcutting off the check.

Another part of the invention resides in the provision of a total-addingmechanism for cash-registers, which is actuated by means of connectionswith a longitudinally-movable operating-shaft, on which is mounted torotate therewith a stationary type-wheel adapted to present the typecorresponding to the amount to be registered in such a position as tomake, an impression on a check-strip, also on a continuous detailtransparent strip, by means of an automatically-operated hammer strikingsaid strips against the face of the type, between which hammer and typethe strips are previously interposed, a suitable inking-ribbon alsobeing interposed between the strips, and mechanism for advancing thestrips after being printed, one of these strips formingacontinuousdetail of all of the registrations printed, which forms a check on thetotal-adding mechanism, while separate impressions of each amountprinted on the checkstrip are cut off and deposited at a locationconvenient to the hand of the operator.

Further details of this invention will be hereinafter fully described,and then defined in the appended claims.

I clearly illustrate my invention in the accom panyin g drawings, whichwith the characters of reference marked thereon form a part .of thisapplication, and in which drawings similar characters of referenceindicate like parts throughout the several views,in which Figure 1 is atop plan View of the mechanism comprising the present invention, thesame showing the top of the case removed.

Fig. 16 is an elevation ofthe disk, which is integral with the sleeve, which has formed at one endthe pinionwheel adapted to mesh with the sliding rackbar. Fig. 17 is avertical longitudinal sectional view through the operating-shaft and thestepped shells mounted thereon, showing in elevation, partly in dottedlines, the platen and means for operating same. Fig. 18 is a top planviewof the rack-bars andlugs thereon. Fig. 19 is a sectional viewlongitudinally through a rack-bar, showing one bar in elevation.

Reference now being had to the details of the drawings by letter, Adesignates the casing of the register, which is shown only in section inorder to better illustrate the oper ative mechanism of the rcgister,andmounted in said casing is the frame B, which supports the operativemechanism, in the upright portion of which frame is journaled the hubportion 0 of the hollow cylindrical shell C, which has its marginal edgeformed into a series of steps 0 This shell is provided for a purposewhich will be hereinafter described in detail. The hub portion 0'' isjournaled in a bearing Cicarried by an upright portion of the frame,which bearing is interposed between the end of said shell 0 and the hubC of the type-wheel C Mounted in the hub is one end of theoperating-shaft D, which is splined thereto, while the opposite end ofsaid shaft is mounted in a sleeve D in which the inner end of said shaftis splined. From this construction it will be seen that the said sleeveand shaft D and the shell 0, with hub C, are caused to rotate together,the inner end of the operating-shaft being contracted and allowed alongitudinal or telescoping movement within said sleeve, whichlongitudinal movement is necessary in the operation of my check printingand adding mechanism, said shaft having also a longitudinal movementthrough the shell O, to which it is splined, as will be readilyunderstood. Keyed or otherwise mounted on said shaft, so as to rotatewith the same, are the hollow cylindrical shells E and F, which havetheir circumferences broken away and stepped,as at E and F,respeetively. These steps are provided to actuate a trip member which inturn causes mechanism to be operated which will effect the registeringof a purchase amount, andeach step of the shell E, which is provided toregister a purchase amounting to one dollar or more, represents anumeral-21 6., in r at E of the shell, at which place the cylinder isentirely cut away. This blank space extends about a portion of thecircumference of the head of said shell. The second shell F, ofslightlydarger diameter than shell E, is utilized when it is desired toregister purchases amounting to cents and is similarly constructed, buthas more steps, the first of which represents the purchase amount offive cents and the highest ninety-five cents. This shell has also ablank space F having no steps, which space is equal to that taken up bythe steps on the shell E, and the two shells E and F are so keyed orotherwise fastened to the operating-shaft with relation to 1 each otherthat when the steps on the shell E, for instance, are turned forengagement 1 with the lug on the sliding raek-bar beneath the blankportion of the shell F will be presented adjacent to said lug, so as topass over the same without striking it, and vice versa, when the shell Fis brought forward for engagementwith a lug which will actuate mechanismdesigned to register purchases amounting to cents. Keyed to the shaft Dis a wheel I, which has a series of recesses 1 about its circumference,the walls of which recesses taper, as seen at 1 Mounted on a suitableportion of the frame of the register is a block J, (shown in Fig. 5 ofthe drawings,) the forward end of which, or the end which is adjacent tosaid wheel I, is tapered, as seen at J. This member J is held in ahorizontal position and is provided as a guide over which the recessesin said wheel I are adapted to pass, so as to hold the wheel and theshaft carrying the same from rotation,

while the operating-shaftis being moved longitudinally for the purposeof registering a purchase amount. These recesses are disposed at equaldistances apart about the circumference of the wheel, and one isprovided for each step on the shells which are keyed to theoperating-shaft, so that at whatever position the shaft is stopped inthe act of indicating any purchase amount the wheel I will hold theshaft rigidly while the registering mechanism is being operated.

At the outer end of the operating-shaft is a knob D, whereby said shaftmay be rotated and worked longitudinally. to be mounted theindicating-pointer, which On this shaft is is adapted to register with adial carried on the outer face of the register, which parts, however,are not shown in the drawings, as

they form no part of the present invention,

but are included in and covered by my pending application, Serial No.(557,268. This shaft also actuates an indicating-dial Z, which .is shownin section in Fig. 5.

Mounted in the frame of the machine and IIO adapted to have alongitudinal movement in suitable guideways therein are the rackbars Nand N. These rack-bars are provided with teeth n on their under faces,and the bar N, which is provided to actuate mechanism for registeringpurchases amounting to dollars, has two upwardly extending lugs or tripsN and N the former of which is longer than the lug N for the purpose ofallowing the steps on the shell E, which is of less diameter than shellF, to strike said lug N and advance the rack-bar carrying the same, saidrack-bar bein returned to its starting position by the end of the shellF. The second of said rack-bars N has twolugs N and N the former ofwhich is shorter than lug N for the purpose of allowing the steps of theshell E to pass freely over said lug when the steps on the shell F areturned, so as to engage with the lug N carried by said rack-bar N. Asthe shell F returns to its starting position its rear end strikesagainst the lug N carried by the rackbar N, which causes a rotarymovement to be imparted to the registering mechanism, indicatingpurchases from five to ninetyfive cents. The said rack-bars N and N areheld in place in any suitable manner, and the rearward throw of each ofsaid bars may be limited by means of a plate or any other suitable stopdisposed across the path of the racks, and the forward throw of each ofsaid rack-bars is limited by a particular step C of the shell 0, whichstep may be turned in such a position in the rotating of theoperating-shaft so that. it will come in alinement with the end of theparticular rack-bar which is drawn forward when the shaft is pulled outin the act of registering a purchase amount. Mounted on the rods (1carried by the shell 0, which rods pass through the head of the shell F,are coiled springs G which are provided to throw the shaft carrying saidshells back to its normal position. The steps on the shell 0 are soarranged with reference to the steps on the shells E and F that theywill always have the same relative position to one another, and when anyparticular step on the shells E and F is turned to strike a lug toactuate one of the rack-bars a corresponding step 0 on the rotary shellC will be turned so as to come in alinement with and be presented in thepath of the lug carried by the particular rack-bar that is being drivenforward, thus forming a stop against which step 0 the lug strikes tolimit its forward movement.

Journaled in a portion of the framework of the machine is a sleeve P inwhich is journaled the shaft P. This shaft P is journaled at its outerend in the bearing P as shown in Fig. 10 of the drawings.

Integral with one end of the said sleeve is a pinion-wheel P, the teethof which are adapted to mesh with the teeth on the under side of therack-barN. At the opposite end of said sleeve is the enlarged integraldisk Q, in the circumference of which disk is a notch Q which is shownclearly in Fig. 15 of the drawings, in which said notch is shown asengaged by the free end of the spring-actuated pawl Q which is pivotedto a stud Q mounted on the stationary post Q forming a part of the frameof the register. Mounted in an aperture leading from the bore of saidsleeve through the shouldered portion Q forming a part of the disk, is aspring-actuated pawl Q, held at its farthest outward throw by means ofthe coiled spring Q which is clearly shown in Figs. 10 and 15 of thedrawings. Loosely journaled on the shaft P is a registering-wheel R,which carries a series of numerals about its circumference, and securelyfastened to or integral with said registering wheel are the tworatchet-rings S and S, which are provided with external and internalteeth, the teeth on the external circumference of which rings arereversely arranged with reference to each other, as clearly shown inFig. ll-of the drawings. These ratchet-rings are shown as being held tothe registering-wheel R by means of bolts R, but may be fastened theretoin any other suitable way, if desired; or said reversely-arranged seriesof ratchet-teeth may be formed, if desired, of a part of saidregistering-wheel. Pivoted on a common pivot Q with the pawl Q, isasecond pawl Q which is adapted to mesh with the teeth S on thecircumference of the ring S. This pawl Q is held normally in engagementwith said teeth by means of the spring Q (Shown in Figs. 11 and 15 ofthe drawings.) The free end of said pawl Q engages with theteeth S onthe outer periphery of the ring S. It will be noted that the free end ofthe pawl Q when in its normal or starting position also engages with thesingle notch Q in the periphery of the disk forming a part of the sleeveP. It will also be noted that the pawl Q normally engages with the teethon the inner rim of the ratchetrings S and S and is allowed to turn idlyover the ratchet-teeth when the rack-bar N is drawn forward in the actof rotating the sleeve carrying said pawl, but to engage with the teethon the inner circumference of said rings when rotated in the oppositedirection, which causes the registering-wheel R to rotate in effecting aregistration. The pawl Q engages with the teeth in the outercircumference of the ratchet-ring S and allows the registeringwheel R,connected to said ring, to rotate only in one direction, that directionbeing the same as the motion which is imparted to the sleeve as therack-bar actuating the same is thrown back to its starting position. Asthe rack-bar N is thrown back to its starting position and in suchmovement rotating the sleeve the registering-wheel will be carried withthe sleeve until the pawl Q is allowed to fall into the single notch Qand as the said pawl Q falls into the notch Q it will also fall into oneof the teeth of the ratchetring S, which tooth has come in alinementwith said single notch in disk Q, which will form a positive step andprevent any further rotary movement to the registering-wheel. Looselymounted on said shaft 1? is a bail T, the ends of which are journaled,one as at T and the other at T about the circumference of the sleeve.Mounted in this bail is a shaft T on which is carried a collar T havinga suitable set-screw and a spring-actuated pawl T, is either carried byor forms a part of said collar, and said pawl is actuated by means of aspring T (shown clearly in Figs. 10 and 13 of the drawings,) one end ofsaid spring engaging with the bail and the other bearing against saidpawl. Mounted on the upright post 13 of the frame on a stud B is ananglelever H, one end of which is notched, as at H, and has anupwardly-projecting arm 11 which is adapted to project into the path ofand be struck by a lug R carried by the registering-wheel B, said lugbeing adapted to strike the arm 11* at each revolution of theregistering-wheel R. The outer swinging portion of said bail is adaptedto normally rest in the notched portion H of said lever II, and as saidlever is tilted on its bearing B the portion of the lever supporting thebail is thrown back and allows the latter to fall by gravity to theposit-ion shown in dotted lines in Fig. 13 of the drawings.

Keyed to the shaft P" is a disk G, which is similar in construction tothe integral disk Q, forming a part of the sleeve P This disk G isprovided with a spring-actuated pawl G, mounted in an aperture in theshoulder of said disk, and securely fastened to said disk are the tworatchet-rings G and G which are held to a registering-wheel J by meansof the bolts J. Said ratchet-ring G has a series ofratchet-teeth G aboutits outer circumference and a row of teeth about its innercircumference, and about the circumferenoe of the ratchet-ring G is aseries of teeth G, which teeth are reversely arranged to the teeth G"about the outer circumference of the ratchet-ring G while the innercircumference of the ratchetring G has teeth G which are in alinementwith the teeth on the inner circumference of the ratchet-ring G In theseteeth G and G is adapted to engage the pawl G, which pawl rides idlyover the ratchet-teeth when the disk G is rotated in the forward throwof the rack-bar N, which rack-bar, meshing with the pinion P keyed tothe operating-shaft P, will cause the latter to rotate. Integral withsaid disk Gr is the flange G which has a single notch G" in itscircumference, which notch is normally engaged by the pawl K, which pawlis also designed to engage with the teeth G6 on the outer circumferenceof the ratchet-ring G This pawl K is mounted on the stud K, which formsa common bearing for the pawl M, the ends of which pawls are connectedby means of a spring 1V which spring is provided to throw the free endsof said pawls in engagement with the two series of reversely-arrangedteeth G and G.

The rear end of the pawl K carries a lug K which engages in an elongatedaperture h in the lever H. By this connection of the pawl K to lever H,the free end of which pawl normally engages with the teeth G on theouter circumference of the ratchet-ring G said pawl will be thrown outof engagement with said teeth as the lever 1-1 is thrown back by meansof lug R striking the arm H engagement with the ratchet-teeth is held insuch position, while the bail T is at its lowest limit, as shown indotted lines in Fig. 13 of the drawings, in which position the outer endof the bail will hold the lever H in its outwardly-tilted position,while the registering-wheel J is being advanced one notch, which partialrotation of said registeringwheel is effected by the followingmechanism: Mounted on the end of the shaft T is Said pawl K being thusthrown out of a roller \V, which is disposed in the path of v thewedge-shaped end of the longitudinallymovable member V, which at eachoutward pull of the operating-shaft is driven forward by the wheel Istriking against the end of said member V, and when the bail carryingsaid wheel is at its lowest limit the inclined or upper edge of thewedge-shaped member V strikes said wheel and raises the latter to itsnormal position or to the position shown in Fig. 13 of the drawings.Secured to said member V is a spring V, the other end being attached toa stationary part of the frame, which is provided to draw back saidmember to its starting position. As the bailT, to which may be secured acoiled spring X, in order to assist in pulling down said bail to itslowest limit, is caused to fall, the pawl carried by the bail will turnidly over a single tooth and be in readiness to rotate theregistering-wheel, to which is secured theratchetring engaged by saidpawl, and as the member V is driven forward the bail is raised to itsstarting position and the free end of the pawl K is thrown into one ofthe notches in the ratchet-ring G". 'When the ratchet-rings are in thisposition, in which the pawls K and M are engaging with thereversely-arranged teeth,about the circumference thereof, theregistering-wheel J is securely held from rotation in either directionand retained in such position until the registering-whcel R, whichcarries a lug R makes a complete revolution, which will again trip thelever ll, allowing the bail carrying the pawl to fall, so that its pawlwill engage with an adjacent tooth in the ratchet-ring G in readiness toimpart a partial revolution to said registering-wheel J as theextensible shaft is operated or until said registering-wheel J is causedto effect a registration in its rotary movement by the manipulation ofthe rackbar N, which meshes with the pinion P keyed to the shaft P, inwhich latter case when the shaft P is rotated in the act of reg-'stering purchases amounting to dollars, the one-notch flange G willturn with the shaft,

throwing the pawl K out of engagement with the single notch of theflange G also out of engagement with the tooth in the ratchetring G theslight tilting movement thus imparted to the pawl K being allowedwithout dropping the bail T by reason of the lug K carried therebyhaving a limited play in the slot in lever H. Upon reference toFig. 1 ofthe drawings it will be observed that the said wedge-shaped member V isdriven forward by means of its rear end being struck by the wheel I asthe extensible shaft is drawn out.

Mounted on a shaft U, which is supported by brackets on the frame of theregister behind the registering-shaft, is an angle-wheel U, which hasintegral therewith a cog-wheel U and said angle-wheel has a plurality ofteeth U between which the circumference of said wheel is concaved, as iscommon in intermittent gear-wheels, a View of a similarly-constructedwheel being shown in Fig. 12 of the drawings. Secured to the frame ofthe registering-wheel J is a disk J which has a single notch J in"itscircumference, and secured to said disk J is a notched plate J, having anotch J which is in alinement with the notch J in said disk J The curvedsurfaces between the teeth U on said angle-wheel are adapted to contactwith the circumference of said disk 3 and at each revolution of theregistering-wheel J, carrying the disk J one of the teeth U of saidangle-wheel will engage in the tooth J and at the same moment one of theteeth of the cog-wheel U will engage with the notch J in plate J and inthe further rotation of the said disk J it will be noted that theangle-wheel will cause a partial revolution to be made to thepinionwheel mounted on the shaft U, and after the notch J in said diskhas passed the tooth U of the angle-wheel a concaved portion of theangle-wheel will ride on the circumference of said disk and prevent thelatter from imparting a rotary movement to the angle-wheel until saiddisk has made another complete revolution.

Mounted loosely on the shaft P is a third registering-wheel J", which isprovided with a disk J secured to its face adjacent to the pinion-wheelU This disk J 7 has a series of cog-teeth about its circumference, whichare normally in mesh with the teeth of thepinion U and at each partialrevolution of said pinion-wheel the registering-wheel J will be causedto rotate one notch. Mounted on the outer face of the registering-wheelJ is a disk J having a single notch, (not shown, but similar to notch Jand said disk has secured to its face a plate J havinga single notch J,(shown clearly in Fig. 12,) which notch is in alinement with the singlenotch in the circumference of the said disk J Mounted on the shaft U isan angle-wheel J which is integral with a pinion-wheel J which angle-wheel and pinion are similar in construction to angle-wheel U andpinion U hereinbefore described. The concaved surfaces between the teethJ of the angle-wheel J are adapted to contact with the circumfer-' enceof said disk J during the rotary movement of the latter, and when thenotch in said disk J comes opposite a tooth J on the angle-wheel J saidtooth willturn down into the notch in the disk J and one of the teeth ofthe pinion J will turn in the notch in the plate J thus causing apartial rotary movement to the pinion, which in turn transfers itsmotion to a fourth registering-wheel J which is provided with a disk Jwith a se ries of cog-teeth about its circumference. About thecircumference of these registering-wheels are arranged numerals in suchan order that all of the registrations which are made in the operationof the register will be added up and be visible at suitablesight-apertures in a casing surrounding said registering-wheels, butwhich casing has not been shown.

Mounted within the casing of the register is a frame 1, supporting theoperating-rollers of the check-printing mechanism. In this frame areheld the spindles 2 and 3, on which are j ournaled the spools 4 and 5,on which the inking-ribbon 6 winds. This ribbon, which unwinds from onespool 4E and winds upon the other 5, passes from spool 4 underneathspool 5, thence over roller 7, and in a horizontal direction over roller8, thence back underneath roller 9, and is wound up on spool 5.

The strips of paper to be printed are designated by numerals 10 and 12,the former of which is the check-printed strip and is mounted upon aspindle 13. (Shown in Fig. 1 of the drawings.) The spindle 13 is looselyheld in place in the slots 14, (shown in Fig. 1,) similar to the slot 23(Shown in Fig. 2.) By having said spindle carrying the check-printingstrip loosely held in said guide-slots the spindle may be readilyremoved to replenish the supply of paper, and the roll of thecheckprinting strip will work down by gravity, keeping the strip tautover the roller 15, mounted stationary in the frame underneath thespindle 13. Journaled in the upright posts 16, secured to the casing ofthe register, is the diagonally-disposed roller 17,0ver which .the paperis fed and caused to make a rightangled turn in its forward progress.Said check-strip after passing over the roller 17 passes under roller 17over the roller '7, thence underneath roller 8, and over roller 18,after which it is cut off by an automaticallyoperated knife, which willbe presently described.

The continuous detail-strip 12, which is preferably of a transparent orpartially transparent paper, unwinds from the roller 19, journaled on aspindle 20, which is mounted on a portion of the frame of the machine,and said strip is passed underneath the roller 9, above the two folds ofthe inking-ribbon, underneath roller 21, over the roller 22 and unneaththe friction-roller 23, and may then pass over a roller 24, and allowedto accumulate within the casing, from which it may be removed at anytime in order to compare the detail amounts of the purchases, whichstrip may form a check upon the total-adder, which has been hereinbeforedescribed and which forms a part of the present invention. This strip ismade, preferably, of a transparent or nearly transparent i'naterial, sothat the impressions of the type which are printed on the under surfaceof said strip may be read through the strip as positive numerals.Fastened to and turning with spool 19, on which thetransparentdetail-strip is wound, is a cogwheel 25, the teeth of whichmesh with the teeth of a cog-wheel 20, which is secured to the spindleS, on which the inking-ribbon is wound. Mounted on the spindle 27is afriction-wheel 28, to which spindle is secured the cog-wheel 29, theteeth of which are adapted to mesh with the teeth of the cog-wheel 30,and mounted in the upwardly-extending arms of the frame is a shaft 31,which carries at its inner end a cog-wheel 32, designed to mesh with theteeth of the cog-wheel 30, while at the outer end of said shaft is keyedan operatinghandle 32 Mounted on the said shaft 31 is a ratchet-wheel 31having teeth about its circumference which are designed to engage with apawl 33, which is pivoted on the frame of the machine, and has securedat its rear end a spring 3%, which spring is adapted to normally throwthe free end of said pawl into the teeth of said ratchetwheel, so as toallow the shaft 31 to rotate only in one direction for the purpose ofimparting a rotary movement to the rollers, and mechanism for advancingthe strips of paperbeing printed and the inking ribbon, in the coursesdescribed. Integral with the cog-whee1,which is carried by the spindle27, is a shoulder 36, which has a single tooth 37 on its circumference,and integral with said shoulder is a cam 38. Said tooth 37 at eachrevolution of the wheel carrying the same is adapted to mesh with one ofthe notches 39 in the intermittent wheel 40, which is carriedon theshaft carrying the roller 22and causes a partial revolution to saidroller 22, which will advance the strip of paper 2, which has beenpreviously printed. The outer circumference of said roller and thecontact-roller 23 may have a.portion of their circumference milled andbetween which the said strip of paper 12 passes and is slightly advancedat each partial revolution of the roller 22. Mounted on the pivots 42 ineach side of the framework of the check-printing mechanism are the lugs43, which are integral with the plate 44. The said plate has its upperend forked, forming arms 45, which extend underneath the friction-roller23, which roller is held yieldingly against the roller 22 by means ofsprings 46, which are held to the framework by means of the screws J(Shown clearly in Fig. 8 of the drawings.) By this provision of theplate 44: it will be noted that when the lower end of the same is pushedforward said friction-roller 23 is raised from contact with the strip ofpaper 12, and the roller-'22 allows said strip 12 to be drawn forwardover the rollers when it is desired to tear the strip off containing thedetail registrations that have been printed on the same. Mounted on themain operatingshaft and adapted to rotate with the same is a typewheel Cabout the circumference of which are arranged the type 4-7, the type forthe figures representing purchases from naught to ninety-live centsbeing arranged on one side of the central line about the circumferenceof said wheel, while the type representing purchases amounting todollars are arranged in a parallel row on the opposite side of thecentral line, whereby when purchases amounting to dollars and fractionalparts thereof are printed upon the check and detail strips the figuresrepresenting the total amount will read in the same line. Mounted in theupright portion of the frame supporting the registeringshaft is a blockor bar 48, which has a slight longitudinal movement, and the rear end ofsaid block or plate has an upwardly-projecting portion 1-0, which is disposed in the path of the wheel I, said upwardly-projecting portion beingadapted to be struck by said wheel I when the extensible shaft drawssaid wheel out to its limit. The opposite end of said baretS is reduced,forming a shoulder 50, which is designed to contact with the projectingend 51 of the platen 5:, which is pivoted at 53 to the upright portions54: of the framework. The outer free end of said platen has an enlargedand flattened portion 55, which as the operating-shaft is driven forwardcauses the platen to be thrown up against the type on the type-wheel,and as the detail and check printing strips, together with the two foldsof the printing-ribbon, are interposed between the platen-head and theface of the type it will be noted that impressions of the type will beprinted on the upper face of the check-printing strip and on the underface of the detail transparent strip, thus making the numerals which areprinted on the detailstrip clearly visible as positive numerals throughthe paper. Securely held in a horizontal position is a plate 56, havinga cutting edge 57, against which the pivoted knife 58 is adapted toshear as said knife turns on its pivot. To the outer end of said knifeis connected one end of the spring 59, the other end of said springbeing secured to the casing, as at 60, this spring being provided tohold the said knife normally in the position shown in Fig. 6 of thedrawings. At the pivoted end of said knife is a projection 61, which isdisposed in the path of the cam 38, and at each revolution of the wheelcarrying said cam the latter is adapted to strike against the projection61 and cause the check on which the amount of registration has beenprinted to be cut off, said check after being cut falling to anaperture, from which it may be readily withdrawn. In order to allow theroller 18 to tarry slightly while the knife is cutting the check-strip,it is my purpose to flatten a portion of the roller 28, as shown at 62,which flattened portion is presented adjacent to the roller 18 while theknife is being actuated by the cam tripping the same. The ribbon whichwinds about the roller 8 is guided thereon between shoulders on saidroller, as seen in Fig. 8, which latter is mounted in arms 8 which arecarried about the spindle supporting the roller 27. The crank 32 isallowed to be turned by depressing the spring-actuated lever 70, whichis pivoted to the frame, so that its free end will rest normally in thepath of said crank, but may be depressed by the thumb of the operator ashe grasps the crank-handle, thus allowing the crank to make a completerevolution.

In operation the shaft which carries the indicating-pointer is firstrotated so that the pointer will indicate the amount desired to beregistered, and as said shaft rotates the particular step on the wheel Eor F, which step corresponds with the particular numeral sought to beregistered, is turned so that the said step will come in alinement withthe particular rack-bar N or N, accordingly purchases amounting todollars or cents are to be registered. In the rotation of the shaft theshell 0, which is keyed to it, will present the proper stop in alinementwith the lug at the forward end of the rack-bar which is to be drivenforward. The type-wheel C which has about its circumference the type,will be turned so that a numeral or numerals corre sponding to theamount which is to be registered will come on the under side of the saidwheel and directly above the platen 52, between which platen andtype-wheel have been previously disposed the detail and checkprintingstrips, together with the inking-ribbon. l/Vhen the shaft has beenrotated so that the parts connected therewith will as sumo the positiondescribed, the machine is in readiness to have its extensible shaftpulled out, and in the latter operation one or the other of therack-bars carrying the lugs on their upper surface will be drivenforward to such a distance as will be lim ited by the particular step onthe shell 0 which is. disposed in the path of the lug carried by theplate being driven forward. As the shaft is drawn forward the wheel I,carried thereby, is adapted to strike against the longitudinally-movableplate or bar 48, which will cause the outer end of the platen to bethrown up against the strips to be printed and the interposedinking-ribbon with suflicient force to cause an impression to be made onthe check-printing strip as well as on the detail transparent strip. Onthe return movement of the operating-shaft to its starting position therack-bar which has been drawn forward will cause theregisteringmechanismtobe operated. Forinstance, if the rack-bar N isbeing actuated to register purchases amounting to less than one dollar,in the forward movement of said rackbar N the sleeve P will be caused torotate outward or in a direction which will cause the pawl Q to turnidly on the ratchet-teeth on the inner circumferences of theratchetrings S and S. As the disk forming a part of said sleeve beginsto rotate the pawl Q will be thrown out of the single notch in saiddisk, also out of the path of the teeth in the ring S, and will be heldout of engagement with said teeth S as the end of said pawl rides on thecircumference of the disk. WVhen the rack-bar has been withdrawn to itslimit and the operating-shaft returns to its starting position, the rearend of the shell F, coming in contact with the lug at the rear end ofthe rack-bar N, will cause said rack-bar to return to its startingposition and rotate the sleeve in a reverse direction from that impartedto it as the rack-bar is drawn forward. In said reverse motion which isimparted to the sleeve it will be observed that the registering-wheel Rwill be caused to rotate with said disk forming a part of the sleeve byreason of the pawl Q engaging with the teeth of the ratchet-rings S andS. The pawl Q which normally engages with the reverselyarranged teethabout the circumference of the ring S, will prevent any backwardrotation of the said registering-wheel, and the pawl Q which is ridingon the rim of the disk, is held out of engagement with the teeth on thering S, allowing the ratchet-rings and registering-wheel, together withthe disk, to rotate until the single notch Q in the disk comes back. toits starting position, in which position the free end of the pawl Q willbe thrown into the notch and will prevent any further momentum to theregistering-wheel. This operation is repeated in making successiveregistrations, and at each revolution of the registering-wheel R, whichcarries a lug R thereon, said lug R will strike against theupwardly-projecting arm H of the lever II, which arm is disposed in thepath of said lug, and said lever will be tilted, allowing the bail T,carrying a pawl engaging with the teeth on the outer circumference ofthe ratchet-ring G to fall in the position shown in dotted lines in Fig.13 of the drawings. As said lever H is tilted out so that its arm willclear the lug R the pawl K, which has a lug K engaging in an aperture inthe lever, will have its free end thrown out of the notch, and theregistering-wheel G is in position to be rotated one notch when theoperating-shaft is drawn forward the next time. As the shaft is drawnforward the wheel I will strike against the wedgeshaped member V, theinclined edge of which will strike against the roller W, carried by theshaft in the swinging bail T and raise said ball to its normal position.As the bail is being raised the pawl carried thereby will cause theregistering-wheel to rotate one notch, which movement imparted to theregistering wheel G will cause the highest amount which can beregistered on the wheel R (which is ninety-live cents) to be transferredto the wheel J. \Vhile the bail is in position shown in dotted lines inFig. '13 it will be observed that the free end of the pawl K will beheld out of the path of the teeth about the circumference of the ring Gwhich will allow said ring G to be driven forward as the bail is raisedto its starting position. As the bail reaches its highest limit theshoulder H on said lever is thrown underneath the same and the pawl K isautomatically thrown back into a tooth in the ring G, thus positivelyholding the registeringwheel Jfrom further rotation. At each revolutionof the registering'wheel J, which has a disk secured to its face, one ofthe teeth U on the angle-wheel, which is made integral with thepinion-wheel U will engage in the notch J in the circumference of saiddisk secured to the registering-wheel and cause a partial revolution tobe imparted to said angle and pinion wheel. As the tooth on theangle-wheel engages in the recess J one of the teeth of the pinion-wheelU will engage in a notch J which is in alinement with the notch J insaid disk, which will allow the pinion to turn freely. As the pinionmakes a partial revolution the teeth thereof engaging with the teeth onthe disk secured to the registeringwheel J will cause the latter to makea forward revolution one notch, sufficient to register the highestamount contained on the registering-wheel J. At each revolution of thewheel J the registering-wheel J is caused to make a partial revolutionby a similarly constructed and arranged angle and pinion wheel, as willbe readily understood. \Vhen it is desired to actuate the rack-bar N ineffecting registrations amounting to dollars, the registering-wheel R isidle, and the shaft P as the said rack-bar N is drawn forward willrotate, and with said shaft the registeringwhee1 J will turn outward,the pawl carried thereby will ride idly over the teeth on theratchet-rings G and G and the free end of the pawl K will be thrown outof the notch which it engages and will ride on the circumference of theflange G of said registering-wheel G, the tilting movement sufficient tothrow the pawl out of the notch which it engages being allowed by reasonof the lug carried at the rear end of the pawl having a slight play inaperture 7L in the lever 11. As the rack-bar N is driven back to itsstarting position by means of a lug carried thereon being struck by therear end of the shell F the shaft P will be rotated in the oppositedirection and the pawl engaging with the ratchet-teeth on the inner rimof the rings G and G will cause the registering-wheel J, connected tosaid rings, to rotate with it until the notch in the flange Gr comesback to its starting position, in which position the spring-actuatedpawl will be thrown into the notch and positively hold theregistering-wheel from further rota tion. This operation maybe repeatedin each successive registration of numerals amounting to dollars untilthe wheel Jhas made one revolution, and at each revolution of theregistering-wheel J a partial revolution will be imparted to the wheel Jin the manner which has been described.

It will be observed that when registrations are being made of purchasesamounting to dollars without using the registering-wheel R the lever Kand hail supported thereby are idle and serve no function whateverexcepting when registrations are being transferred from the wheel R tothe wheel J. By providing the pawls engaging with theoppositely-disposed teeth in the ratchet-rings and the notch in thecircumference of said disk and flange a positive lock is provided toprevent rotation of said disk and registering-wheels in either directionuntil the pawls are operated in the manner described for the purpose ofregistering the amounts.

After the purchase amount has been printed the operating-handle carriedon the shaft 31 is rotated, said rotary movement being allowed bydepressing the spring-actuated lever 70, as seen in Fig. 1, which isinterposed in the path of the crank connected to said shaft and thedetail and check strips are drawn forward, the check-strip, which passesbetween the rollers 18 and 28, being automatically cut off by the knife58, which is actuated at each revolution of the wheel carrying the cam38. At each revolution of said wheel carrying the cam 38 the lug 37,which is integral with a shoulder 36, will cause a partial revolution tobe made to the wheel 22, which will advance the detail-strip asufficient distance to receive the next imprint of the registration thatis made adjacent to the last impression, so that the amounts printed onthe detail-strip will be adjacent to one another and in columns.
